About twice a week, sometimes more often, Dr. Jordan Moskoff attends to a sex accident at his Chicago emergency room: objects stuck in places they shouldn’t be, broken penises caused by inept lovers and even severed organs they jokingly call “Lorena Bobbit” cases.

“[Penile] rings are really problems,” Moskoff told ABCNews.com. “That should be a public service announcement: Don’t use anything that doesn’t have a hinge or is not made of rubber, or it’s not coming off.”
